Silent rupture: unmasking a posterior capsular rupture in a seemingly uncomplicated cataract.

Cataract surgery is typically considered routine, especially when preoperative things are normal. We present a rare intraoperative complication where the cataractous lens nucleus dropped into the vitreous cavity immediately following viscoelastic injection-prior to capsulorhexis-in a patient with Fuchs' heterochromic iridocyclitis and no overt signs of zonular instability or capsular pathology. The case underscores the need for heightened surgical awareness in seemingly uncomplicated cataract cases, particularly in the presence of subtle clinical history. Surgical management included anterior capsulorhexis, pars plana vitrectomy, lensectomy and sulcus intraocular lens (IOL) implantation. In cases of total cataract, it is imperative to implement preventive strategies despite seemingly unremarkable preoperative findings. Preparedness with alternative IOL options, such as a three-piece IOL, and ensuring the availability of a vitreoretinal surgical team will be helpful if anything seems abnormal.
